Well, well, well.
I got the whole problem solved. Turns out you guys and the DVArchive programmers were right on the money.
I looked at the "the "linkie-poo" in post #35 of this thread", and the first thing that interested me was the slow connection remark by Jeff D. So then I looked at the
SourceForge FAQ's and went to work on a couple of the suggestions about how to optimize my network efficiency.
In the "Playback FAQ's", I found that a "Windows Person" had had some luck with pinging his PC to RTV connection to find the maximum MTU, (mine turned out to be 1470), and then did a few regedits to optimize for the value.
In the 'General Troubleshooting FAQ's', I found that someone named John Nadu had run Dr. TCP and changed the MaxDuplicateACK's to 2, and that he turned off TimeStamps as well, both of which I eventually did. It turned out that the third regedit, for TimeStamps and for WindowScaling, (Tcp1323Opts = 3) may have been superseeded by the Dr. TCP changes, which I did second, and which returned TimeStamps to off.
I also updated my Linksys Router's firmware, and changed/enabled the MTU there to the same value (1470) as my regedit, then rebooted.
And all's well with the world.
I didn't have any luck with just the tweaks from the "Playback FAQ's", which I did first, but when I found the "General Troubleshooting FAQ's" Dr. TCP optimizations, everything started to work great.
I never noticed the fact that the tab for "Served Shows" in DVArchive shows two streams for the 5040 shows and a single stream for a 4040 show until I started working on this problem.
This may be why the program never stressed the ethernet network until I started trying to run my new 5040/rtvedited shows.
By the way, the show that I rtvedited and streamed to the 5040 was from "The Discovery Channel" "Shark Week" entitled "Anatomy of a Shark Bite".
It's really a fairly good documentary. It seemed a little gratuitously violent and gruesome at first, but after watching it a few times, some of the statements and ideas that the scientists, engineers and victims had held a few very interesting insights. Not gimmicky at all in retrospect.
This is a show about the scientist Dr. Eric Ritter, who waded with Bull Sharks even at night and where there is lots of chum, for such a long time finally got bitten.
I remember when I was a kid in Florida there was a shark fishing tournament and the paper reported that the winner was a fisherman who caught a 1000 lb. Bull Shark FROM THE BEACH, IN THE SURF, probably a 12 footer since the 8 ft. fish that attacked Dr. Ritter was estimated to be 400 lbs and almost killed him.
And I used to swim there all the time, right next to the fishing pier when I was a kid. I guess I did have enough sense, even as a kid, to keep my eyes open for fish (prey) and for sharks of course, and not to swim in cloudy water. Not because I knew that that was unwise, because I also swam in the Bayou, which had tannin in the water and was dark even in the day, but because I was a little squeamish about crabs, jellyfish, and seaweed etc.
Lucky me I guess, because back in the late 60's there were a lot more sharks and fish in the water than there are now.
